SPEED REGULATOR.

Application filed August 17, 1922. Serial No. 552,362.

To all whom it may concern:

Be it known that I, CHARLES H. SMoo'r, a citizen of the United States, and resident of Point Pleasant, New Jersey, have invented certain new and useful Improvements in Speed Regulators, of which the following is a. specification.

My invention relates to speed regulators.

The figure is a diagrammatical, vertical view in partial section of one embodiment of my invention.

In the figure, steam engine 1 receives its motive fluid through pipe 24 in which is inserted throttle valve 19. Pulley 2 of engine 1 drives pulley 27 by means of belt 3. Shaft 37 of pulley 27 drives bevel gear 5 which meshes with bevel gear 6. The speed of the engine is thus transmitted to spindle 9, which rotates in bearing 26. Spindle 9 is rigidly attached to oil container 10, having blades or vanes 20--2O inserted in its lower part. Inoil container 10 is located disc 11 having blades 40-40. The disc is connected by rod 12 to beam 41, rod 12 being articulated at point 23 where it is attached to beam 41. Beam 41 rotates around pin 13 held by hearing 42. Spring 14 hearing on beam 41 is adjustable as to tension by means of screw 15. Rod 17 pivoting at point 16 on beam 4-1 operates throttle valve 19. Casing 8 in which bevel gears 5 and'6 are contained, is kept full of oil for lubricating purposes. Oil container 10 is full of oil. At the center of the top of the container 10 is a vertical column or extension 50. Orifices 2222 allow oil to flow into and out of upper part of oil container 10. The top level of the oil shown at 51 may be at any elevation in the extension, the purpose of the extension being to insure that the container itself is full of oil, as it is the purpose of this invention to have the disc 11 entirely immersed in the liquid and to not act in any respect as a float. The diameter of this extension is so small as compared with the container itself that the centrifugal effect of the liquid in the extension has no effect upon the forces controlling the disc.

The speed of steam engine 1 is transmitted by gears 5 and 6 through spindle 9 to oil container 10. When the engine speeds up, the speed of the oil in the container is increased and oil is caused by centrifugal force to flow out from under disc 11 thereby creating a partial vacuum under the disc which has a tendency to depress the latter. Disc 11 being brought down operates beam 41, which in turn operates throttle, valve 19 through rod 17. Blades or vanes 40-410 ins'erted in disc 11 prevent the oil in the upper Part of oil container 10 from rotating.

It is to be observed that the oil container 10 is entirely filled with oil and that an extension 50 is provided to insure that it shall be so filled. It is obvious also that the operation of the governor is in no way affected b the height of the oil in extension 50. ore or less liquid will not affect the accurate performance of the governor. Moreover, the vertical position of the disc 11 does not re uire adjustment. The rise and fall of the disc 11 is due solely to the static difference in pressure on its two sides due to the fact that the liquid under the disc is rotating while the liquid over the disc is not rotating and/it is in this feature that my invention is to be distinguished from the prior art. It is to be noted also that no use is made of the buoyancy of the disc. It will be apparent, therefore. that I have produced a governor of the liquid type which is not dependent in its action on the amount or character of. the liquid or the weight or position of the disc. Such a governor has only the one adjustment, namely, the tension of the spring or its equivalent.

I do not wish to be restricted to the embodiment of my invention illustrated herein, inasmuch as to all skilled in the art it is obvious that my speed governor is applicable to all the uses to which this type of apparatus can be adapted. I do not wish to be restricted to oil as any suitable liquid may be substituted therefor.

I claim:

In a speed regulator, a rotatable liquidtight container having a central vertical column rising therefrom and opening thereinto to insure complete immersion of the governing members, the said container provided with vanes for producing rotation of the contained liquid, e non-rotating disk inside the container with space around it ullowing free communication from one side of the disk to the other and having vanes for preventing the rotation of the liquid, the said disk capable of movin r axially due to the difference in pressure a ove and below it, the vanes on the container and the vanes on the disk being on opposite sides of the disk so as to create such difference of pressure, a shaft for the disk movable axially with respect to the container, and connecting mechanism from saiid shaft for controlling a source of ower.
